To aZZ whom, it may concern:

Be it known that I, DURELL O. PEASE, a citizen of the United States,residing at Hampden, in the county of Hampden and State ofMassachusetts, have invented a new and useful Improvement in Heads forContinuous Drawing and Twisting, of which the following is aspecification.

My invention relates to a head for continuously drawing and twisting asliver of wool or cotton; and the invention consists in the combinationand construction, as hereinafter described, and more particularlypointed out in the claims.

My invention is fully illustrated in the accompanying drawings, in whichFigure I is a front end view of my device with a part broken away. Fig.II is the same complete. Fig III is an end view the reverse of Fig. I.Fig. IV is a section upon the dotted line as w of Figs. I and II. Fig. Vis a detail view in plan. Fig. VI is a top view of the complete devicein operative position, with sufficient of the supports and driving-beltsto show the relation of parts; and Fig. VII is a perspective view ofaframe containing a number of my improved heads in position for use.

A B are two rubber-faced rolls journaled in walls a b in a case, 0. Theroll A has permanent bearings, and is provided with a gear, D, securedto its axis or arbor outside of the wall b. The roll Bis held in closecontact with the one A by means of a follower, E, forked to bear againstopposite journals of said r01l,and provided with a spring, H, interposedbetween its back and the inner wall of case 0. The journals of roll 13are received in elongated slots in the walls a b, and the action ofspring H is to always, through follower E, keep th surfaces of the rollsin contact.

The point of contact of rolls AB is,as shown, coincident with atransverse line through the center of the case 0. The outside posteriorportion of case 0 is reduced to leave a cylin- (No model.)

der-surface d, as seen in Fig. III, to be engaged by the cogs g of shellG. Shell G is held in its proper position relative to case 0 by means ofa screw, 71, therefrom, having its end pass into an annular groove, 1',in surface 0, as -shown in Fig. IV. The outside of sections 0 G areprovided with grooves to receive the belts I K.

M is a web upon the face of case G, perforated centrally and depressed,as shown in Figs. II and IV, and which keeps the roving in the properplace between the rolls A B, and also serves as a guard to protect theinterior ofthe head from dust and lint, which would otherwise soon clogup its inner mechanism. 0 is a trumpet-shaped surface within case 0,having its apex close to the inner surface of rolls A B, and its mouthcoinciding with the rear end of case O,as seen in Figs. III and IV.

The interior configuration of case 0 given by the surface 0 not onlycloses the case with web M to shut out particles of flying matter fromthe gearing and journals within said case, but preserves the end ofroving from injury and permits it to be safely taken to a bobbin out ofline with the axis of the head. The head when journaled as shown in Fig.VI has the case 0 and shell G driven by belts I K at different speeds,and it will be seen that the rolls A B,beside their rotation on the axisof the head rotated by belt I, have rotation on their axes by contact ofgear F with the cogs of section G,rotated by beltK at a greater speedthan the case 0, so that an end of roving passing into the head would betwisted and drawn simultaneously, and so that the proportion of thetwist to the draw would depend upon the relative speed of the sections 0G of the head.

The main purpose of my invention has been to enable the ends of rovingto pass continuously to the bobbins from the condenser, and therebyavoid the necessity of the manipulation and mechanism common with mulesand jack frames.

In Fig. VII a frame containing ten heads is shown. The ends m arerepresented as coming from the condenser, (not shown,) and after passingthrough the guide-rolls L are drawn and twisted by the heads,and fromthem pass directly to the bobbins P, (indicated in the drawings.) Therelative speed of the sections of the heads is governed by cone-pulleysT T, with a belt, Y, connecting said pulleys. This belt may be shiftedby hand or by any ordinary form of belt-shifter. The spindles of saidpulleys T rotate pulleysVW,having, respectively, the endless belts I K,which belts rotate the sections G of the heads, so that the positivespeed of the heads and the relative speed of their sections isdetermined by the I claim is l 1. The improved drawing and twistinghead, consisting of a case, 0, adapted to rotate in bearings, tworubber-faced friction-rolls journaled in said case, a gear, D, on theaxis of and the shell G, mounted so as to rotate on case 0 and having atoothed surface engaging gear F, substantially as described.

2. In combination, aseries ofdrawing-heads each consisting of onecylindrical section carrying a pair of drawing-rolls,and another sectionrotatively mounted thereon and having a gear adapted to drive thedrawing-rolls through intermediates,a frame on which said drawingheadsare supported, two endless belts, I and K, one engaging theroll-carrying sections and the other engaging the roll-driving sectionsof the drawing-heads, two shafts, each bearing a conepnlley and abelt-pulley, the belts I and K, passing over thebelt-pulleys,respectively, and a belt connecting the cone-pulleys, allsubstantially as described.
